47RE Governor Pressure Solenoid 1998-99, new and ready to install. Fits the 47RE. Ships fast from the USA.
If you drive a 1998 or 1999 Ram 2500 or 3500 with the 47RE behind a 5.9L Cummins or an 8.0L V10 and it has started taking off in second, holding first too long with a trailer behind it, or setting governor pressure codes, this is the parts list for that repair. These years span the switch from the 12-valve to the 24-valve Cummins, and both engines use the same electronic governor in the transmission. The kit replaces every part of that circuit in one pan drop: a heavy-duty governor pressure solenoid (Borg-Warner OE 4617210), the governor pressure sensor or transducer (OE 56027720), an output speed sensor (OE 4800879), a transmission filter (OE 52118789), a cork-and-rubber pan gasket (OE 2464324) and the governor solenoid housing block gasket (OE 4886333AA). The kit is new, Dodge-branded, made in the United States and ships from New York.
The 47RE has no shift solenoids for the lower gears. First, second and third are selected by shift valves in the valve body, and the force that moves them is governor pressure working against throttle pressure. In these trucks the governor is electronic: the computer pulses the solenoid ground to bleed line pressure down to the value it wants, reads the result through the sensor, and corrects many times a second. Commanding more duty cycle gives less pressure. At a stop the target is zero so the transmission downshifts to first; it rises about 1 psi per mph, and above about 40 mph the solenoid is shut off so the pressure holds the upshifts. If the output speed sensor signal drops out, the computer has no road speed and stops controlling governor pressure, which is why that sensor is part of this kit.
Hook up a scan tool and drive the truck while watching desired and actual governor pressure; the two should track each other and both should drop to zero when you stop. A gauge on the governor pressure port tells you whether the sensor is honest. Pressure at a stop points at the solenoid or a leaking governor body. Erratic pressure that will not settle can also come from a poor-quality replacement solenoid, so if a part has already been changed, test before assuming the new one is good. Check the transmission relay feed and the sensor ground too. Our Ram 3500 Cummins shift problems guide and 47RE common problems and fixes walk through these checks.
This kit is listed for 1998-1999 A518 (46RE) and A618 (47RE) transmissions in Dodge, Chrysler and Jeep vehicles; for the 47RE that is the 1998-1999 Ram 2500 and 3500. The six parts carry the same OE numbers as our 1996-97 kit, because the early governor hardware did not change until 2000. For 2000 Chrysler moved to a rectangular plastic-bodied sensor, while 1999 and earlier units use the sensor with an oval connector. A rebuilt or swapped transmission may not match the truck's year, so check the sensor plug before ordering, or send us your year and VIN. See every part for this transmission on the 47RE collection page.
Drain the pan, remove the pan and filter, and unplug the governor connector. The governor body unbolts from the transfer plate under the valve body, so there is no need to pull the valve body. Swap in the new solenoid and sensor with the new housing gasket, lubing the O-rings with ATF+4 so they seat without tearing. The output speed sensor screws into the back of the case from outside. Fit the filter and pan gasket, refill with ATF+4 only and set the level hot. The OD and converter lockup solenoid is right next to the governor body, so if the truck also has overdrive or lockup complaints, the 1996-99 47RE TCC and overdrive solenoid can go in on the same pan drop. If gauge tests point at worn valve body bores instead, look at the 1997-2002 47RE valve body.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The six parts carry the same OE numbers: solenoid 4617210, sensor 56027720, output speed sensor 4800879, filter 52118789, pan gasket 2464324 and housing gasket 4886333AA. The early governor hardware stayed the same through 1999 and changed for 2000.
Yes. It is listed for 1998-1999 A618 (47RE) transmissions, and the governor circuit is in the transmission, not the engine, so it applies to both. It also fits V10 trucks with the 47RE in those years.
Look at the governor pressure sensor connector. 1999 and earlier sensors have an oval connector; 2000-up sensors are rectangular and plastic-bodied. If your transmission was swapped, the sensor tells you which kit fits, or send us your year and VIN.
Governor pressure is not dropping to zero at a stop, so the shift valves stay in the upshifted position. A sticking solenoid, a bad sensor, a leaking governor body or a missing output speed sensor signal can all cause it, and a gauge test sorts them out.
ATF+4 only. A pan drop does not drain the converter and cooler, so refill to the dipstick and then check again hot in neutral, adding a little at a time.
